UGI® 4410
UGI® 4410 introduction
UGI® 4410 is a superduplex stainless steel designed for applications in highly corrosive environments. It has the following advantages:
very high mechanical properties;
excellent resistance to different types of corrosion in aggressive environments.
In its delivery condition (solution-annealed), the structure of UGI® 4410 is two-phase: ferrite + austenite. It contains between 45% and 55% ferrite and is free from intermetallic phases and chromium carbonitrides.
UGI® 4410 is highly susceptible to the precipitation of intermetallic phases that degrade mechanical properties (reduced toughness) and corrosion resistance. The sigma phase precipitates at between 600°C and 1000°C, after a holding time of a few minutes. The sigma precipitation phase at between 350°C and 550°C also poses a risk of embrittlement. Consequently, the temperature at which the grade is used must be limited to 300°C.
Equivalent material: DIN 1.4410, DIN X2CrNiMoN 25-7-4, UNS S32750, ISO 4410-327-50-E, ISO X2CrNiMoN25-7-4.EN X2CrNiMoN25-7-4
